Wireless mobile technologies have improved enormously, One of the main developments is the emergence of 4G technology. It’s a word that you’ve surely encountered in your daily life, but what is 4G? And is Xiaomi Redmi 9A 4G capable? We are going to answer these and other questions related to Xiaomi Redmi 9A 4G technology in the following article.
is Xiaomi Redmi 9A 4g capable?
Yes. The Xiaomi Redmi 9A is 4G enabled
Checking the existence of 4G on Xiaomi Redmi 9A
Nowadays, it is inevitable to purchase a 4G-enabled device, because most internet users require a good internet connection. To know whether the phone is 4G enabled you can use multiple means.
An easy method when you have the device in your hand is just turning on the cellular data, if the Xiaomi Redmi 9A 4G data is on, then you will see an icon at the top of the display, in the indication bar. It might be 4G, 4G+, LTE, or LTE+ according to your carrier.
The absence of that sign means that you are not using 4G at that particular moment, and it doesn’t signify necessarily that your device doesn’t support 4G. And that takes us to the second option.
Check your phone specifications on the manual, or in the device package. If you don’t have any of them you can still check that on the official site (or any other credible website) using the device name or model number.
Another way is to check the settings: Go to your settings and find network mode, usually as follows: Settings > Cellular (or Mobile Data) > Cellular Data Options (or Mobile Data Options). If your phone has 4G you will find 4G option or LTE. If you don’t see either of them, then your smartphone doesn’t support the standard.

Get to know what is 4G on Xiaomi Redmi 9A
4G describes cellular network technology. It was identified by the ITU (International Telecommunication Union) and used by phone carriers. To name a system 4G it should meet some specifications.
The ‘G’ in 4G stands for generation, and 4 means the fourth one, following 3G and preceding 5G. 4G networks must grant internet speeds much better than 3G, they also grant low latency, which is essential for some uses such as gaming services.
The most widespread protocols identified by ITU as a 4G are HSPA+ and LTE. Xiaomi Redmi 9A 4G and 4G in most devices today use one or both of them, which makes 4G the fastest most utilized cellular network.
What are the advantages of 4G on Xiaomi Redmi 9A?
4G was established to offer a more reliable internet connection on mobiles, and that’s truly what it did. 4G technology presents much improved downloading and uploading speeds than 3G.
The average 3G speed ranges from 1.5 to 9 Mbit/s, while the average 4G internet speed ranges between 15 to 90 Mbit/s, it can reach as high as 900 Mbit/s.
Another vital criterion of 4G, is its low latency. We can simplify latency and say it’s the time needed to transfer data or the delay between the action and the actual response. Low latency means a better user experience. 4G has 100% better latency than 3G. The average 4G latency is 50 ms.
With the aid of the VoLTE standard, 4G now allows better voice quality in phone calls and gives users the ability to browse the internet while making calls.
All of these advantages combined with the low cost of 4G expanded the use of Xiaomi Redmi 9A 4G technology, to include better video conferencing, online gaming, and other real-time interactions.
What are 4G bands? and which bands are supported on the Xiaomi Redmi 9A?
Before talking about 4G bands, you should know what is a frequency. Frequency is the repetition of an event, it is measured in radio communication by hertz (Hz).
Since radio waves are used for multiple reasons besides 4G (radio broadcasting and Aeronautics as examples), it is vital to decide which frequencies must be used for what reason. Otherwise, radio waves will contradict, and it would be a mess.
Governments and ITU allocated each range of frequencies (called bands) to specific uses.
What you should consider as a user of Xiaomi Redmi 9A, is whether it supports the bands provided in your area by your local cellular operator or not. The Xiaomi Redmi 9A 4G supported bands are :
1, 2, 3, 4, 5, 7, 8, 20, 28, 38, 40, 41 – International;1, 3, 5, 8, 40, 41 – India;.
